The Amplifier

…is an understatement. In addition to being a highly efficient amplifier, CA280DSP features a very advanced DSP, automated room EQ, sound masking and high/low impedance mode. All easily accessed remotely.

Designed for AV installers and integrators, CA280DSP is packed with features and easy to use. It offers excellent sound quality in a compact housing and comes with full protocols for third party integration.

Simply access the amplifiers Wi-Fi network. Load settings for your Cornered loudspeakers, Add room EQ, Delay, RMS Compression, Dynamic EQ or even Sound Masking if needed. Run the speakers in high or low impedance - or run one channel with a line of 100V speakers and connect an 8 ohm subwoofer to the other channel. The choice is yours.

The CA280DSP will take it from there and with sleep mode and a fan-free design, chances are you will never see it again.

The amplifier section uses a very efficient switch mode power supply and two Class D output stages with ultra-low distortion and a full set of circuit protections including over-current, over/under voltage, output, DC. Furthermore, an efficient heat dissipation system and over-heat protection ensures uncompromising reliability.

The top grade 48 kHz/24 bit DSP engine is capable of sophisticated loudspeaker processing. There are 5 EQ’s on the input channels and 30 EQ’s on the output channels. Each band can be switched to Bell, Lo/Hi-Shelving with variable Q. The HP/LP filters offers slopes from 6dB/Octave up to 24dB/octave including Bessel, Butterworth and Linkwitz-Riley.

With the built-in Auto EQ, CA280DSP can sweep the room and set the EQ automatically. Fast and efficiently. And with 2x140W @ 4ohm or 8ohm or 1x280W for 70V/100V Direct Drive, the output-to-size ratio is excellent.

CA280DSP excels in performance, ease of use and reliability and is the perfect fit for the Cornered loudspeakers.
